SPECIFICATION forming part of Letters Patent No. 674,079, dated May 14, 1901. Application filed March 131 1901. Serial No. 50,914. (No modem 1'0 all whom it may concern:

Be it known that I, FREDERICK DANNER, a citizen of the United States, residingat Springdale, in the county of Allegheny and State of Pennsylvania, have invented or discovered certain new and useful Improvements in Furnaces, of which improvements the following is a specification.

The invention described herein relates to certain improvements in furnaces for glass pots and other purposes, and has for its object a construction and arrangement of regenerating-chain bers and fines whereby a better regulation of the heat in the melting-chamher is obtained and whereby access can be readily had to all parts for repairs.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a longitudinal sectional elevation of my improved furnace, the plane of section being indicated by the line I I, Fig. 4. Fig. 2 is a transverse sectional elevation on a plane indicated by the line II II, Fig. 4. Fig. 3 is a sectional plan view on a plane indicated by the line III III, Fig. 1. Fig. 4is asectional plan View on a plane indicated by the line IV IV, Fig. 2. Fig. 5 is a similar view indicated by the line V V, Fig. 1. Figs. 6 and 7 are vertical sections on planes indicated, respectively, by lines VI VI and VII VII, Fig. 4.

In the practice of myinvention the melting or heating chamber 1 may be constructed in accordance with rules known in the art for the purpose desired. When used for melting glass in pots, it is formed with openings in its sides for charging and removing the pots and has its floor inclined toward said openings, so that the glass when pots are broken may flow out. Theregenerating-chambersarearranged below the heating or melting chamber, the gas-regenerating chambers being intermediate of the air-regenerating chambers. The gas-regenerating chambers 2 and 3 are connected to their respective ends of the heatingchamber bya series of dues or passages 2 and 3, which merge into common ports 2 and 3 opening into the chamber 1 at opposite ends thereof. The lower ends of the gas-regenerating chambers connect with fines 4 and 5, which extend under and beyond the sides of the furnace. At one end these lines connect with agas main or conduit (5, and the flow of gas from the conduit to the fines is controlled by valves 4 and 5. The valves may be of any suitable construction-e. 9., saucer shape, as shown-and are preferably so connected to an operating mechanism, as the lever 7, that by the shifting of the lever one valve is closed and the other is opened. The opposite ends of these fines are connected to the conduit 8, leading to the stack, and the flow of products of combustion from the lines to the conduit 8 is controlled by valves 9 9. These valves may be of the saucer type, as shown, or of any other suitable construction and are operated by a suitable mechanism, as the lever 10, so that when one is opened the other is closed.

The air-regenerating chambers 11 11 and 12 12 are arranged on opposite sides of the chambers 2 and 3 and are connected by ports or passages 13 13 and 14 14, respectively, to opposite ends of the heating-chamber, said ports opening into said chamber on opposite sides of the gas-ports 2 and 3 and in such relation thereto that the gas and air will thoroughly commingle as they flow into the chamber. The lower ends of the air-regenerating chambers areconnected,respectively, to fines 15 15 and 1t 16, which extend to the stack-conduit 8. These fines are connected at points intermediate of the air-regeneratin g chambers and the stack-conduit to air-inlet boxes 17 and 18. The flow of air from these boxes to the flues is controlled by valves 19 l9 and 20 20, which are connected to a suitable mechanism, as lever 21, whereby the closing of one pair of valves is simultaneous with the opening of the other pair. The airinlet boxes are provided with doors 22, whereby the volume of air flowing into the furnace may be regulated. Valves 23 23 and 24 24* control the flow of products of combustion to the stack-conduit. It is preferred to connect these valves to the mechanism-e. g., the lever 10employed for shifting the valves 9 9 so that both sets of valves may be operated simultaneously.

In describing the operation it Will be supposed that the gas-valve 5, the air-valves 19 19 and the outlet-valves 9 and 16 16 are open and that all other valves are closed, so that gas will flow through flue 4, regenerating-chamber 2, and fines 2 and port 2 to the heating-chamber, where it will mingle with air entering through box 17 and flowing through fines 15, air-regenerating chambers 11 11, and fiues 13 13 to the heatingchamber. The products of combustion flow from said heating-chamber through ports or flues 3 14 14 3 regenerating-chambers 3 12 12*, and fines 5 16 16 to the stack-conduit. By a reversal of the several valves the direction of flow of gas and air into the furnace and of products of combustion from the furnace to the stack is reversed.

By the employment of two pairs of air-regenerating chambers having independent supply-fines and independent connections to the heating or melting chambers the heat in the .chamber 1 can be easily regulated and controlled.

I claim herein as my invention 1. A furnace having in combination a heating or melting chamber, two gas-regenerating chambers,two pairs of air-regenerating chamhers arranged on opposite sides of the gaschambers, said regenerating-chambers being connected to the heating-chamber, fines extending under the gas-chambers and having their opposite ends connected respectively to a gas-conduit and a stack-conduit, valves.

controlling the flow of gas to and from said flues, fines extending from each of the airregenerating chambers to the stack-conduit,

and provided with air-inlet ports intermediate of the stack-conduit and the regenerating-chambers, and valves controlling the flow of air to and of gases from said fines, substantially as set forth.

2. A furnace having in combination a heating or melting chamber, two gas-regenerating chambers, two pairs of air-regenerating chambers arranged on opposite sides of the gas-chambers, each air-chamber being independently connected to the heating or melting chamber, fines extending from the gaschambers over the air-chambers to the heating or melting chamber, flues extending under the gas-regenerating chambers and having their opposite ends connected respectively to a gas-conduit and a stackc011duit-, valves controlling the flow of gases to and from said fines, flues extending from each of the airregenerating chambers to the stack-conduit and having air-inlet ports intermediate of the stack-conduit, and the air-chambers, airboXes having adjustable doors arranged over the inlets, and valves controlling the flow of air and of gases from said fiues, substantially as set forth.

In testimony whereof I have hereunto set my hand.
